Résumé : The fine Nantais Oblong, a melon of Charentais type, was shown to be a source of resistance by antibiosis to the leafminer, #Liriomyza trifolii# (Burgess), Diptera, Agromyzidae. We studied the genetic control of this resistance in F2 and back-cross progenies from the cross between Nantais Oblong and Védrantais, a Charentais line susceptible to the leafminer. Tests were carried out on young plants in plastic cages with controlled infestation. Complete mortality of the #L. trifolii# larvae was used as indicator of plant resistance. Segregation ratios were consistent with monogenic dominant control of the resistance. The symbol #Lt# for #Liriomyza trifolii# resistance is proposed.
